We compare the total energy consumption performance of the proposed algorithm (labelled as `Proposed NOMA') with the interior point method to solve convex problem (REF ) by using matlab toolbox, the conventional optimal algorithm for OMA-based MEC networks [1]} (labelled as `OMA'), and the equal resource allocation algorithm where equal time duration is allocated for different groups and the offloading data is optimally allocated (labelled as `Equal resource').
